WCSTImport

WCSTImport will send this information to Petascope:

rasdaman

Petascope should send to rasdaman:

UPDATE myCoverage AS m SET m[0:720,0:360,0:1, 0:1] ASSIGN VALUES decode($1, "#messages")

#messages should be as follows:

{
  "messageDomains": [
    "[0:0,0:0,0:719,0:360]",
    "[0:0,1:1,0:719,0:360]",
    "[0:0,2:2,0:719,0:360]",
    ..
  ]
}

The messageDomains should be ordered to match the message order in the GRIB file.

The X/Y are required to be the last dimensions as this is efficient and simple (no need to reorder stuff further in rasdaman, besides row-major -> column major for each message).
